yEELAJIER. FOR MOTOR CARS.

Application led March 2, 1921. Serial No. 449,203.

To all whom t may concern.'

Be it known that I, ADRIAN DENMAN- JoNns, a subject of the King of Great Britain, residing at 37 Hartham Road, Holloway, London, England, have invented a new and useful Improvement in Heaters for Motor Cars, of which the following is a specification.

My invention relates to improvements in the construction of heaters for motor cars, and refers more particularly to the foot rest type of heater though it may be applied to any type.

The invention is illustrated by the accompanying drawings which show a heater in the form of a foot rest adapted to be placed on the floor of a motor car.

Figure 1 is a front elevation, Figure 2 is a section showing the lmethod of securing the tubes to the headers, Figures 3 and 4 are sections on the lines A-A, BB, of Figure 1, and Figure 5 shows a detail.

1 to 8 are tubes the outer ends of which butt into sockets formed in headers 9 while their inner ends butt into .sockets formed on each side of a fitting 10. In this fitting are inlet and outlet pipes 11 and 12 adapted to lit into sockets formed in a plate 13 which is let into the floor of the car and into which screw unions 14, 15, the one connected to a tube 16 through which heated air can be delivered to the heater, and the other connected to a flexible pipe 17 by which air can be withdrawn from the heater. Air entering the pipe 11 flows either outwards through tube 1 and back through tube 2 or outwards through tube 5 and back through tube 6 and then either routwards through tube 3 and back through tube l or outwards through tube 7 and back through tube 8 to the pipe 12. The whole apparatus is held rigidly together by means of tie bolts 18 which pass axially through the tubes and are secured by nuts 19 on the outside of the headers.

By reason of this construction tubes of comparatively thin metal may be employed and yet suflicient rigidity is obtained in the whole system.

20 is a board which extends from one header tothe other and forms a shield which prevents draughts of air flowing directly through the heater but guides the current of air in an upward direction on to the passen- When it is desired to place the heater in'V position the' cover is raised slightly and turned through a right angle so that the heater can he placed in position.

After theheater has been removed the cover is lifted slightly and again turned through a right angle so that it covers the holes in the plate 13.

"What I claim is t 1. In a heater for an automobile, the combination of two end headers, a fitting intermediate of the headers, a series 0f tubes be tween the fitting and each header, means for rigidly securing the headers, the hitting and the tubes together, and inlet and outlet pipes both depending from the fitting and adapted to enter sockets in the floor of the automobile.

2. In a heating apparatus for an automobile, the combination of a series of tubes, an inlet pipe and an outlet pipe both depending therefrom, a plate having vin it two sockets adapted to receive the pipes and a conductor adapted to lead hot air to that socket which receives the inlet pipe.

3. In heating apparatus for an automobile, the combination of a series of tubes, an inlet pipe and an outlet pipe both depending therefrom, a plate having in it two sockets adapted to receive the pipes, a conductor adapted to lead hot air to that socket which vreceives the inlet pipe, and springinfluenced means mounted in the plate and adapted to cover the sockets when the heater is removed.

In testimony that I claim the foregoing as my invention I have signed my name this tenth day of February, 1921.

ADRIAN DENMAN-JONES.
